SACK-TURNER. I

Specification of Letters Patent.

Patented July as, rare.

Application filed September 10, 1912. Serial No. 719,683.

" being suspended and secured in any conven ient or desired point upon a vessel, building or other structure for rapidly handling sacks of flour, wheat, and the like, and alternately deflecting the sacks to one or the other ofdivergent chutes or runways, without the aid of an attendant. v

With the above and otherobjects in view, the invention consists in the construction, combination and arrangement of parts, as

will be hereinafter more' fully described, illustrated in the a'cco q and pointed out in anying drawings, the c aims hereunto appended. Y

. In the-drawings: Figuie 1 is a plan viewof'a sack turner, embodying thopresent invention. Fig. 2 is a side elevation of the same. Fig. 3 is a detail section, showing the toggle lever arrangement, showing-the de-.

fiector thrown into its. operative position. Fig. 4'is a similar View, showing the lever folded into its inoperativeposition. Fig.6 is a central vertical section takenadjacent to the The sack (turner contemplated in this invention comprisesv a base or bottom 1, upon which all of the working parts Oftllgdfiflcfi are mounted. This base is of the shape 7 shown in Fig. 1, and also comprises the inwardly converging sides 3, forming the contracting entrance throat of the device, and the downwardly diverging sides 4 which, at their-lower ends, form the outer side walls of the. diverging runwaysor chutes 5 and 6, the inner walls of the runway being rep: resented-at 7. i K

Extending across "the receiving edge of '6 the throat-1s areinforcing strip or metal strap 8, riveted or otherwise secured to'the base 1, and having fastened thereto ring bolts adapted to receive suspending cords or cables, whereby the device as a whole may be swung on board of a vessel and held in anydesired' position. The device is also pro-. vided adjacent tofits lower end with eye gears and also showing one of the site deflectors 11 and 12, the same being 0011- nected by hinges 13 to the sides of the turner.

Connected to each deflector levers 14 and 15', the lever 15 being mounted fast on a rock shaft 16 mounted in suitable bearings 1.7 on one of the sides '4 of the device while connected fast to the same shaft 16 1s a lever arm 18, to'the eX- tremity of which is pivotally connected a connecting rod 19 extending downward and pivotally connected to a lever arm 20 on the outer end of a trip shaft 21. This trip'shaft .is mounted in suitable bearings 22 on the back of the bottom or. base 1, as shown in Fig. 2. a v

The connections just hereinabove described are duplicated on the other side of the turner and cooperate with a second trip shaft 23 which is arranged in a plane parah lel to the shaft 21, but turns in a reverse direction therefrom, the said shafts 21 and 23.

being provided, respectively, with spur gear wheels 24-and 25 which intermesh and therefore cause the simultaneous rotation of said trip shafts in opposite directions. It will now be seen that when one of said shafts is operated upon, theconnections between the said-shafts and the deflectors arcmoved inopposite directions, so that as one deflector 11 is moved inward, the other deflector 12 is moved outward, and vice versa. In order to enable sacks to automatically operate said deflectors, the shaft 21 is'provided with a trip 26 fast thereon and working through an aperture 27 in the base 1. The shaft.. 23' is likewise provided with a trip 28, working through an aperture 29 in the base 1 It will now be seen that as a sack passes down one of the runways orchutes. 5 or 6, it will act on the upstanding trip" and reverse the positions or angles of the deflectors l1 and 12, causing the next sack to pass down the other runway and in turn operate upo'nth other trip, thereby again reversing the a .gles of the deflectors. In this way, the sacks are automatically deflected first to one run.- way and then the other. a

At the discharge end of the turner, pivoted tail gates 30 and 31 are arranged, so as toextend the control over the sacks passing through the runways and direct the same to 11 are toggle the proper points.- These gates may be made of any desired length.

- 32 designates a divider shoe which cn- 'n'ects the upper ends of the inner. walls 7, and is chambered to fit over and form a I housing for the gear Wheels 2 k and 25,

thereby inclosing and covering said gear wheels, avoiding any possibility of the sacks coming into contact therewith and being injured. g

Heretofore, it has been necessary for a 7 man to stand at the discharge end of a chute and manually deflect the bags to one side or the other, requiring great dexterity and c011- stant attention on his part. The device hereinabove described automatically takes care of the sacks and. alternately deflects them first to one side and then the other,

without any attention whatever.

erating connections controlled by said trips,

and'embodying trip shafts geared to turn in opposite directions and each having one of,

the trips fast thereon.

2. A sack turner, comprising a base, a

single entrance throat, divergent runways communicating with the base of said throat,

sack deflectors pivotally mounted at opposite sides of the throat, sack actuated trips arranged in said runways, and deflector operating connections controlled by said trips, and embodying a pair of trip shafts arranged in'parallel planes and each carrying one of said trips, intermeshing gear, wheels fast on said shafts, and a divider shoe forming a housing for said gear wheels.

' 3. A sack turner, comprising a base, a single entrance throat; divergent runways communicating wit-h the base of said throat,

sack deflectors pivotally mounted at opposite sides of the throat, sack actuated trips arranged in said runways, and deflector op crating connections controlled by said trips", and embodying toggle levers connected with the deflectors, trip shafts carrying the trips.

and geared to turn in opposite directions, and connecting rods interposed between the lever arms and the trip shafts and. toggle levers.

In testimony whereof I aflix my signature in presence of two Witnesses.
